Kiri Aluminium, a prominent manufacturer and supplier located in Hamilton, New Zealand, specializes in high-strength Aluminium 2024 Channels designed for tough aerospace, structural, and mechanical applications. These channels are crafted using cutting-edge extrusion and heat-treatment techniques, ensuring they provide outstanding tensile strength, excellent fatigue resistance, and dependable performance even under heavy loads. Known for its remarkable machinability and impressive strength-to-weight ratio, Aluminium 2024 is perfect for precision-engineered components. Kiri Aluminium offers these channels in a variety of sizes and tempers to cater to the needs of aircraft structures, defense equipment, automotive engineering, and industrial fabrication. Each channel is produced with rigorous quality control to guarantee maximum durability and precise dimensions.
Aluminium 2024 Channels are composed of a heat-treatable aluminium-copper alloy that contains approximately 3.8–4.9% copper, along with magnesium, manganese, silicon, iron, and trace elements. This unique blend results in exceptionally high tensile and yield strength, robust fatigue resistance, and excellent machinability post-heat treatment. The alloy remains rigid and stable under stress, making it ideal for critical structural components. While its natural corrosion resistance is moderate, applying anodising or protective coatings can significantly boost durability. Aluminium 2024 is well-regarded for its perfect balance of strength, hardness, and machinability, making it a top choice for demanding engineering environments.
